IMPROVEMENT IVN conn-PLANTES.

To ALL wnoM 1T MAY conocen; n y n y v t Be itknownthat we, JAMES M. `Goanoriand E. GnursrrANsoM, of St. Joseph,.in the county ``of Buchanan,

l and State of Missouri, have invented a new and useful Improvement inCornfIflanters ;`and we do hereby declare that the following isa full, clear, and exact description thereof, which will Venable othersl skilledin the art to. make and'use the same, reference being had to theaccompanying drawings, forming part of` this speeiieaton.`` i Figure 1 is atop or plan view of ourimpr'oved machine. 1

Our invention has for its object to furnish an improved corn-planter,l simple in constrnctionye'ective and accurate in operation, and which shall 4mark the hills so that the planting may be done with `convenience and dispatch,`and without its being necessary to previously mark the ground; and it consists in thenconibination and 'arrangement of thel various parts of the machine, as hereinaftermore fully described. l i

A is the frame of the machine, to the middle part of th forward end of which the `tongue is attached." i l C and D are thewheels. The wheel C revolves upon 'an axle attached 'to the frameA. The'wheel D is rigidly-` attached to its axle E, `which revolves in bearingsattached to the framel A, and which has a cross-bar, F, securely attached to its inner end. G is a pulley, rigidly attached tothe inner end of the sleevel, through whichthe axle,E passes. The pulley `Gr has cogs or pins, I, attached to its inner side, wl1i.h,"whenthesaid,pulleyGfis` f moved inward, take hold of the cross-har F, causing the pulley@ and sleeve Hto be carried with the axle E in l its revolution. J' is a small gear-wheel'attachedto th'e outer end'of the sleeve H` Kis a lever, 'which isz.,

pivoted to the side of the cross-bar L, the ends of which are pivoted 'to the frame A, so that `the JeverK may have two movements, one lateral to throw the sleeve H and clutch-pulleyG into' andout of` gear.' with the bar F and axleE, and the other longitndinalwith the frame A, to adjust the dropping-device `into proper position to commence theV rows. The lower end of the lever K isI made circular, und has teeth formedupou'it fitting into the teeth vof the `wheel J, so that by operating the lever K the position of the dropping-device may be adjusted,-

as required. To the sides of the lower endof thelever Kare attached plates, the lower edges of which are n made circular, and which project alittle below'the teeth formed upon the lowerend of said, lever, so that the.. i said plates may. overlap the sides of the gearswheel J, to enable the lcver'K by its lateral movement to throw l Athe pulley G and cross-bar FV of the axle E into and out of gear with each other;` llpisA acatch, attachedto i the frame Ain` such a position that 4 it may take hold of the lever K when moved into such a position as `to throw the pulley G r into gear with the bar F of the axle E, and hold it securely in place while the machineis l working.` M is a band, which passes around the pulley Gr, and around the pulley N,f.ttachedito the middle part y i t of the `shaft O, soas to communicate `motion from the said 4pulley G to the said shaft. are the seed-boxes,

whichl are cylindrical in shape, and have holes through the centre of their'lower; sides, through which the seed passes tothespouts R, by which it is conducted Vto the ground` directly'in therearfof `theI ploughs or marksS,

which are attached to the forward partof the frame A, and whichmark or furrow the ground for the recepticn of the seed, the` seed being covered by the advance of.the broad" wheels C and l), whichgact as rollers. The

shaft O passes through the seed-boxes P, and has wheels, T, "attached to` it of "such asize las to work freely` .p

within the seedboxes P. The wheels Thave holes formed through their opposite'sides, of such a size as to hold the-proper amount of seed to' form a hill. U are small plates, attached to the bottoms`oftth'e seed-hoxes P, which overlap the inner sides of the rims ofthe said wheels T to prevent any more' seed thanenough to'form a hill from passing into the spouts R. Thc'plates U render it necessary that the spokes of the wheels T should be connected with the rims'near oneV edge, las shown in dotted lines in fig.` 1. To the ends' of fthe. shaft O, which t project beyond the seed-boxes `l?, at the sides of the machine, are ,attached 4bent arms or4 supports, V, having `I holes through their ends through which pass'the markers W. 1L" is a' 'projecticmfoijmed upon lor attached to the central part of the makerbars W within the arms or ends'oil the support V; X are coiled. wire or equivalent springs, coiled aroundthe bars ormarkersW, with .one end resting against .thc projections-wand their other ends against the innersidc's ofthe arms or supports V. The markenbarsWare arranged in such a position that they'may be in linewith the holesin the wheels T, and are of` such a length .that `whenl theshgft '11,a`7s e 2 O revolves, the ends of the markers may enter and mark the ground directly opposite the point where the hill is planted, the springs X enabling them to give should they encounter an obstacle. The ends of the markers W are'made broad orspade-shaped, as shown in iig. 1, so that the marks made by them may be more readily seen.

We claim as new, and desire to secure by Letters Patent- 1. The combination of the lever K gearwheel J, sleeve H, and clutch and band-pulley G, with the crossbar F and axle E, substantially as herein shown and described and for the purpose set forth.

v 2. The combination of the band M, pulley N, shaft O, and wheels T, with each other and with the pulley G and seed-boxes P, substantially as herein shown and described and for the purpose set forth.

3. The combination of the mark-ers W with the shaft 0 and wheels'T, substantially as herein shown and described and for the purpose set forth. 'n
